This invention is also applicable to atank car or'the like adapted to contain gasoline or other likecommodity. 3.0

customaryto apply heat thereto to improve the fluidity of the materialwhen it is desired to discharge the same from thetank, in order thatsuch commodities may readily flow through thenozzle, L

This'invention further and morespecifically relates to heating means forthe discharge nozzle, to the endthat rupture'or fraceQ ture thereof maybe obviated or the danger of such breakage minimized, it having been.found} in practice that frequently the dis charge nozzlewillbecomefilled with water,-

often to the level of the di schargervalve of 45,-;the tank, thewaterremaining in the nozzle Figure 1 is a'sectional view of theimproved nozzle, the same, being appl ed to a tank,

being taken on the line l-l of l Vhenthereceptacle is loaded with mate-lrial which tends to solidify or congeal, it is andfthere becoming frozenwith a resultant rupture orfbreakage of the nozzle, 7 i

It is, therefore, one object. of tl e present invention to provide.adischarge nozzle for,

the exterior of a tank or the like having means for heatingt-he 82,1116.r I I I Lnother object of the invention is to proa tank or thelikewillbe he'atedwith a resultant heating of the tank itself adj acenttheoutlet. L

Q Asbefore-mentioned, one disadvantage'of thedischarge nozzles inpresentday usage is that Water frequently freezes therein resulting inbreakageotthe nozzlenecessitating a replacing of the complete nozzle. Iam aware that it is old to provide heateddischarge nozzles, and I amalso aware that it is old to pro: Vide a jacketed nozzle through which aheat exchange medium is circulated and these have". provensatistactoryfor the purpose of heatmg the nozzl e. It has been foundthat it is desirable to provide discharge nozzle with,

some means which will serve as a resisting ele-.

ment to take up the: expansion of a congealing medium, such means beingcollapsible under pressure less than that requiredto rupture the.discharge nozzle. 1 1 1 v Another bjectot the present invention,therefore, is to provide a discharge nozzle; with an elementpositionedtherein which iscollapsible, ,under pressures lless than:that-re.-

quired, to rupturelthe. discharge nozzle,.said element servingto' resistto ai greatextent the expansion of a congealing mediumt Many otherobjectsand advantages of this inventionwill be apparent-from thefollowing description, taken in conjunction with the accompanying drawngsmrwhich A designates, v aportion of. atank, said tank havinganopening therein for; discharging the contents of theYtank,this-construction being well known intheartatthe present time.Theopening is adapted-toconnect with the discharge nozzle indicatedgenerally as acasting Bwhich is.

i secured to the tank in any suitable or desired manner.

The nozzle B is preferably substantially rectangular'in form or at leastis of greater cross-sectional length than width for the purposeshereinafter described, and is provided with a top portion 1 having athreaded openheaders may be positioned within the nozzle- B adjacent theends thereof and in such a manner that a substantially uninterruptedpassage will be provided from the opening in the tank to the dischargeoutlet 5' thereof.

The means for'heating this nozzle B are clearly shown and compriseclosed headers 6 oppositely and vertically arranged in the nozzle, theheaders being connected together ad'- j acent their upper ends bysuitable means suchas the conduit G shown in Figs. 1 and 2,

said-conduit having threaded engagement at its ends'with an internallythreaded boss? formed adjacent theupper end of each header.

' Theheaders are preferably of the form il lustrated in section in Fig.2 and are formed of material having less strength to resist strains andpressure exerted thereagainst than the material of the, nozzle itself,and said headers each are provided with a concave inner face 8 which,when the headers are positioned within the nozzle B, are alined v withthe opening from the tank and with the discharge outlet; thus providingal'free passage for thecommodity in the tank which passage isinterrupted only by the conduit C which latter, of course, is also aheating element. I

The conduit C is preferably formed of sections 9 and 10 arranged inabutting relation endto end, the meeting ends thereof being welded atthe joint 11. Positioned within the conduit C and overlapping the joint11 is a thimble 12. An inlet pipe 13 is connected with one of theheaders 6 at the lower end thereof, the pipe 13 passing throughan'ropening formed in the nozzle B and being threads edly engaged withsaid header :6, as shown at '14. Secured to the other header 6 anddiametrically opposed to'the pipe 13'is an outlet pipe 15"which extendsthrough the nozzle B as shown and is threadedly engaged with the lowerend of said header 6 as shown at 16.

In the assembly of the device shown in Figs.

' 1 and 2, the thimble 12 is secured within the unthreaded end of thesection 9, with the end of said thimble extending beyondthe section.

The section 9 is then threadedly engaged with the header 6. The header6, with its con-" nected section 9, is inserted into the nozzle Bthrough the outlet 5. The section 10 of the conduit C is then engagedwith the other headers 6 and the latter, with its connected section 10,inserted into the nozzle B and the sections 9 and 10 are then placed inabutting relation at the free ends thereof, the free end of section 10telescopically engaging the extended end of the thimble 12. The abuttingends of sections 9 and 10 are then connected, for example, by welding,as shown at 11.

The headers 6 are each provided with an opening at the lower endthereof, which openings are diametrically opposed when the heaters arein the assembled position illustrated in Fig. 1. The inlet and outletpipes 13 and 15 respectivelyare secured within the openings in the lowerends of said headers and the "device is then completely assembled, itbeing apparent from an inspection of the drawings that theheaders are soarranged as to be positioned outside or adjacent to a direct passagefrom the opening in thebottom of the tank to the discharge outlet.

Fig. 3 discloses a modification of the 1nvention, more specifically, amodified form of header connecting means. As shown in this 'figure, thenozzle B, headers 6 and lnlet and outlet conduit pipes 13 and 15 areidentical with those shown in Figs. 1 and2; The headers 6 of this figureare connected by a conduit D composed ofthe sections .17 and 18 whichare respectively threadedly engaged with the headers 6 and said sectionsare connectedtogether by means of a union 19.

' Itis' desirable that the nozzle be so constructed that asuninterrupted a passage as is possible be provided between the tank andthe discharge outlet of the nozzle, and to this end, as shown in Fig. 4,the headers 6 may be connected by a conduit-E which is secured to eachheader 6 adjacent one side thereof and near-the upper ends. The conduitE may be'of the type shown in F ig. 1 or Fig. 3, as desired. WVith thisconstruction, it is apparent that the commodity in the tank will flowtherefrom and through the nozzle with very little interruption duringits passage, the conduit E beingpositioned off center, or to be moreexact adjacent one side of the nozzle B, thereby providing a largeruninterrupted area forthepassage of the commodity from the tank to thenozzle. The'conduit E has been shown inthisfigure as substantially cir-.

cular, but it isito be'understood that this is merly by way of example,the drawings being most, whereby 'a still greater area might be providedfor the uninterrupted discharge of the commodity from the tank throughthe nozzle. This alsoapplies to theconduit' C shown in Fig. 1.

In use a heating medium such as steam Cil is passed from the pipe 18through the headers 6 and the connecting conduit and then out throughthe outlet 15 from whence the heating medium may be conducted into andthrough suitable coils commonly placed in the bottom of the tank. Itwill be obvious that in addition to heating the nozzle 13, the lowerpart of the tank adjacent the nozzle B will also be heated, thus aidingin maintaining the fluidity of the commodity in the tank, at least thatpart of it adjacent the nozzle;

From the above description, it will be apparent that the dischargenozzle has been provided with an element positioned therein which willserve to resist the expansion of a congealing medium up to a certaindegree whereupon the element will collapse, and the element is so formedthat its collapse occurs at a degree of expansion much less than thatrequired to rupture the nozzle itself. Frequently, the congealing mediumwill not occupy the entire interior of the nozzle, and when itcongeals,instead of being restrained. against an upward expansion, theelement in the nozzle will permit and in fact, force the medium toexpand upwardly rather than in a horizontal direction against theelement, thus preventing a total collapse of the element and alsopreventing a rupture of the nozzle.
